Definitions

  • MICHAEL FANTELL FIGURE 3 Patented Oct. 14, 1952 I UNITED STATES PATENT OFFICE METHOD OF CURLING Michael Fantell, West Orange, N. J.
  • My invention relates to a device for curlin strips, ribbons or strands in order to form a sponge. More particularly my inventionrelates to the formation of metallic sponges.
  • My curling device being adjustable to varying degrees of hardness of the material to be curled, will also accept plastic strips as well as synthetic fibers and will impart a curl.
  • Figure 1 is a diagrammatic illustration of the apparatus and method of curling a metal strip.
  • Figure 2 is a front elevation of the curling device.
  • Figure 3 is a cross section taken on the line 3-3 in Figure 2, showing several positions of the curling device.
  • my device has a spool or roll 5 of wire, strands of plastic or synthetic fibers 6.
  • Nickel silver wire, brass wire, or stainless steel wire may be used. There are many other alloys and types of material which may also be used.
  • This wire 6 may be approximately .005 in diameter. Of course other sizes may be used.
  • the wire 6 is fed into a rolling mill between rolls 8, 9 of high carbon steel exerting a pressure of approximately 250 500 lbs. It may thereby be reduced to a ribbon approximately .0015" thick.
  • the flattening function of the rolls 8, 9 may be eliminated and they will merely be utilized for feeding the wire 6 (or other material) and maintaining tension during the curling process, much less pressure then being necessary.
  • the ribbon I0 is then led through a diamond die II.
  • a carboloy die or other similar die may also be used. This die may have an orifice of approximately .02 5" diameter. The size of the orifice is not critical. After passing through the die II, it is pulled through the opposed. rollers l2, l3.
  • the roller 12 is preferably of cast iron and the roller l3 of rubber. Up to this point, the strip ID has been maintained under tension through the pull of the rollers l2, l3.
  • the tension is relaxed and the wire is permitted to form curls l4 and is wound on the spindle l5.
  • a slot I6 in the spindle serves to hold the end of the curled ribbon Hi.
  • the directions of revolution of the various rollers is indicated by the arrows.
  • the speed of the spindle 15 should be approximately one-third the speed of the pulling rollers l2, 'l3 so that the wire l4 may curl.
  • the die II is positioned in a holder ll where it is held in place by a set screw Ill.
  • the holder I! is angularly adjustable being held in any desired position by the set screw [9.
  • the position of the holder and the die is positioned with respect to the path of the ribbon ID by raising or lowering the upright 20 on the bar 2
  • the upright 20 is fixed at any point by the set screw 22.
  • is constantly reciprocated so that the wire 10 is fed into the puller-rolls l2, [3 at varying points and is thereby not caused to wind on the spindle l5 all at one point. If, however, it is desired that the wire Ill be wound on the spindle [5 in a ball all at one point, the holder 2
  • variable factors encountered in curling a metallic ribbon Ill or other material are:
  • variable factors aforementioned may be compensated for and any desired degree of curl effected.
  • the method of curling a strand comprising passing a strand under tension through a hole through a die having sharply defined edges at both ends of the hole, positioning the hole in the die transversely to the path of the strand whereby the strand tightly and sharply bends at a material angle over each of the edges, and releasing the strand to curl.
  • the method of curling a strand comprising passing a strand under tension through a diepassage, said die-passage being a hOle through a die having sharply defined edges at both ends of the die-passage, positioning the die-passage transversely to the path of the strand whereby the strand is frictionally engaged with the edges 4 of the die-passage and bent at a material angle over both edges, and releasing the strand to curl.
